Each Facebook user is automatically restricted to one vote, according to Woobox, and users will not have to authorize apps in order to vote using this method.

On the page admin side, the same user data will be available as for contests that deploy the vote button.

Woobox said in a blog post announcing the feature:

“Why is this a big deal?” you ask? Because voting doesn’t have the same engagement potential as liking does. Liking is more social — and more apt to end up in your fan’s News Feeds — resulting in higher engagement levels and increased traffic to your Facebook page. Asking fans to like a photo or video as a means of voting provides the opportunity for that content to live outside of the confines of the contest. Depending on the individual’s privacy settings, content that they like could show up on their Timeline, providing a whole new set of eyeballs access to your contest.
